How exactly does the "Strange Part: Domination Kills" count?
Solution 1:
It will only count when you "dominate" an enemy for the first time. When you hear that familiar sound that indicates a domination, it should increase your counter by 1.
Subsequent kills on a dominated enemy will not increase the counter for the part. However, that same player can remove the domination by:
- switching teams, then switching back
- leaving the server, then rejoining
- getting revenge
If any of these three things happen, the previous "domination" will be wiped, allowing you to dominate the player again, if you wish.
